To aZZ whom it may concern: l

Be it known thut'l', FREDERICK E. GARL- SON, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in. Vacuum-Bottle Supports, of which thefollowing is e specification.

This invention relates to a support for the Wells ofe vacuum bottle embodying features of novelty and advantage.

7 lu jthe drawings-Figure 1 is a, sectional side view. The vecuum bottle is equipped with a support made in eccordenccwith my invention. Fig. 2 is u sectional view on a line r-2 of Fig. 1. Fig. 8 his perspective the wells or the bottle, which is of usual construction, the walls being connected at the neck and requiring a support at or near the bottom to hold them rigi to prevent break- My invention is concerned with the confirmation of the support which comprises a strip of spring metal 5, the ends of which are folded over-upon itself to form clips 6, 6, in "which are secured the ends of strips 7, 7, material which is a non-conductor of heat. In the manufacture of vacuum bottles, it

is quite impossible to prevent slight vurie tions in the distances between the Wells, no

cessitoting a careful fitting of supports so as to properly breoethe Walls. By this invention it is possible to readily produce a support of propei thiizlmess by winding about the clips as much of the strips '7 as may be needed to fill thespece between the two Walls. Any additionul amount over that required can be readily torn or cut 05. If

desired, two strips can be secured in each light spring action and permits of such slight distortion as may be necessary to fit the support in place, and then tends to assist in holding it in position.

I claim as my invention:

1. A support for the Walls of a vacuum insulated vessel comprising a metallic clip formed by bending itself, and a sheet of heat-non-conducting material wound about seid clip with an end secured therein.

2. A support for the Walls of a vacuum insulated vessel comprising a pair of clips connected by a resilient liar and a strip of heat-non-conducting material, secured in each clip and adapted to be Wound trueabout. v

3. A support for the walls of a "vacuum insulated vessel comprising a resilient our and a strip of heat-non-conducting materiel secured at each end of said her and adopted to be Wound thcreubout to a greater or less extent.
